To all whom it may concern. Be it known that I, CYRUs A. Haas, cit-1- .zen of the United States, residing at $t.

Louis, State of Missouri, have invented cor-1 tain new and useful Improvements in "Water Heaters, of which the following is a full,

clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in water-heaters; and it consists in the novel details of construction more fully set forth in the specification and pointed out in the claims,

Fig. 5 is a vertical middle section of the outer shell or casing on the line 5-5 of Fig. 2, the inner boiler being left in elevation;

Fig. 6 is a combined elevational and sectional detail of the upper portion of the boiler or water circulating member of the heater; Fig. 7 is an enlarged horizontal section on the line 7-7 of Fig. 5; Fig. 8 1s a '1 vertical sectional detail of 'thefree end of tank.

Referringi to the drawings, and for the present to spots a conventional reservoir or water-tank, 1, the cold-water supply pipe tapping'tbe bottom thereof, and 2 the hot-water pipe which dips to the bottom of the tank as well understood in the art. By means of an elbow 3 or equivalent connection the pipe 1 is con pled (through the union 3) to the pipe 4 forming the depending intake of the wateroirculating member or boiler 5 of my improved heater. ln the present embodiment of my invention the boiler 5 is confined in a casing comprising an outer shell 6, an-iniier shell 7, and an intermediate heat insulating or heat non-conducting layer 8 of asbestos or its equivalent, the component parts of said casing being united frictionally or otherwise by any mechanical method known to the art. The clischar o pipe 9 from the boiler 5 passes through tie top of the outer casing whore it is connected through a union or coupling 10 to the circulating pipe" 11- which taps the top of the tank A. The outer casing (6, 7 8) is closed at the top with the exception 0' the flue o )ening 0 from which leads the exit or as no 12, the bottom-of the casing being li cwiscclosed save for the gas intake opening 0 for the insertion of the burner pipe 13 and for the admission of air for assisting in the combustion of the gases discharging from the burner. The openings 0, are diagonally opposite one another as shown.

To insure the longest possible traverse for the combustion products and hot gases through the heater, and to cause the same to intimately hug the walls of the boiler 5, the following provision is made:-Disposed about the peripheral walls of the boiler in planes preferably (though not necessarily) at right angles to its axis, are a series of fins or annular (or equivalent) ribs 1 1 whose peripheries are disposed along the surface of a cylinder-(the boiler 5 itself being cylindrical), said tlues being suitably spaced apart and being distributed the full length of the boiler between the pipes 4 and 9. Clamped at intervals to the fins, and on opposite sides of the axis of the boiler are substantially semi-annular deflecting plates or batllcs 15, the opposite faces whereof carry fingers or lobes 16 disposed preferably in staggered relation. whereby a battle may be readily and frictionally secured to any fin. It will be seen that the fingers or lobes pro- IatcntedNov. 18, 1913.

igs. 1 to 9 inc usivc, A represively on opposite sides'of the axis of the boiler, three such baffles being shown in the "illustration (Fig. The bafiie fills one-half the space between the boiler and outer shell or casing so that the products of combustion in striking the battle are deflected and causedtocross over to the opposite side of the space traversed thereby. The baffles are i just sufliciently short of a complete semi-cir-.

cle .to permit of the insertion between their adjacent ends of a vertical snugly-fitting strip or deflector member 17, spanning the space bet-Ween the fins and outer shell, there being two such strips at points diametrically opposite one another as shown (Fig. 2). These strips are preferably supported by terminal bends or lugs 17 resting on top of.

the top baflie (Figs. 2, 5), though they may be detachably supported in any other convenient or suitable mechanical manner. The pipes 1' and, 11 may suflice'to secure the heater to the tank A, but if insu'fiicient, the

heater may be additionally supported in any manner appealing to the skilled mechanic.

To prevent back flashing of the flame when the burner is low I provide the discharge end of the burner pipe 13 with a diaphragm or rib 18 spanning diametrically the opening of the pipe as shown (Figs. 4, 5, 8). In otherrespects the burner is of the Bunsen variety, except that the air intake openings h are of considerable size to afiord a maximum influx of air to the gas component, which is supplied through the hexagonal or polygonal tip 19 at the discharge end of the gas supply pipe '20 beyond the usual cock or valve 21. The tip 19 has a drive fit in the pipe 13, passages 17 being left between its faces and the inner wall of the pipe for the influx of air (Fig. 9).

The operation of the heater will be read ily understoodfrom the foregoing description and is substantially as follows :The

cook 21 being opened the gas (or equivalent vapor) is allowed to flow into the burner 13 where it is ignited by the insertion of a lighted match or taper into the opening 0'. The hot gases and combustion products before they can escape through the flue 12 must necessarily traverse the space between the boiler h and outer shell in which traverse they not only impinge against the several fins (which afford extended surfaces of contact), but being deflected by the horizontal baffles 15 they are caused to pass transversely first in one directicnand then the other. it

being remembered that the successive bafl'les nor/aces areon opposite sides of the axis of the boiler.

Again, and as illustrated to best advantage 7 in Fig. 7, the vertical strips or baffles 17 spanning as they do the space between the outer edges of the fins 1a and the inner wall of the outer shell constrain the products deflected by the baflies' 15 to pass through the passagesa (Fig. 2) between the inner edges of the strips and the outer wall of the boiler and thus hug the boiler walls. In this way the contents 'of the boiler (which is-in free communication with the tank A) becomes rapidly heated and a rapid circulation sets up sothat in a very short space of time the tank A. is full of hot water. The general is substantially indicated by the arrows in Fig. 5. 5 The hot water of course rises tank, the cold waterleaving the tank from the bottom through the tee 22 and entering the boiler through the pipe 1 as quite obvious from the drawings. By the'time the gases have traversed the circuitous path'defined for them by the fins, and horizontal and vertical deflecting members as aforesaid, they have parted with the majority of their heat units, and when they finally escape from the fiue'12 they are comparatively cool.

In Fig. 10 the heater is shown detached and not connected to a water tank. In that case I employ thesame as a steamer, the

' through the pipe 11 and discharges into the cold water being admitted to the boiler through the pipe 1' provided with a valve V,

the steam generated being allowed to discharge through the pipe 23 for steam baths or other domestic purpose. In other respects scribed, and the same reference numerals are used to designate parts corresponding to those shown in the other views.
